I have now had my Explorer since November. I have most things repaired.

1998 Ford Explorer, 4.0 SOHC





ABS Sensor light - Went to a junk yard and pulled a set from the newest explorer that was there,cleaned them both before installing, issue is resolved.

(1st lesson learned )
I lifted my vehicle with a jack, and pulled passenger wheel off. ABS sensor was pretty straight forward, and I was not going to be under the vehicle - so I did not put it on my jack stands (BAD), jack slipped, I instinctively pulled away, but vehicle caught my should, and had a good bruise and soreness for a almost a week. Never work with a vehicle with any lift and wheels off without using jack stands.

Check Engine light has been coming on. Had the p071 and p074

I picked up some MAF cleaner, looks nice and undamaged. Still have been intermittently getting the CEL on. I pulled the air duct work off an cleaned the
Throttle body as best I could (was ugly), also pulled and cleaned the throttle position sensor, and the Idle air control valve since I had everything off.
I pulled a spark plug to check them out to see if they needed replaced. They looked OK. Put everything back together and was popping the CEL frequently.
Now I am thinking that my MAF was probably bad, so i tested it out by unplugging it as vehicle was running, vehicle bogged down but did not die.
I stopped by the parts store, just to go ahead and get a new pcv valve, ran the code again to see if anything had changed.

(Lesson 2) - Don't get stuck on a code as the only issue, it popped up a P0122 code (Throttle/peddle sensor low input) I researched this, and found that I had not tightened the sensor back on quite enough.

I am CEL free for now, will give it a few days before I consider everything a success.


Also, After replacing my PCV valve out, I noted an open connection right next to where the PCV valve goes, looks like it should have a hose connected to it, but not sure what it is. Anyone, I could not get a good picture of it last night but I am attaching some pics of the general reference point to its location.

1 is the location of the PCV

2 is the location of the random open connection that looks like it should have a hose connected to it

Can you post a better picture of this missing part/hose?

I will try to do that today , it was kinda dark in my garage last night when changing the PCV, its the first time i noticed it.
 






And yes, jack stands are very nessasary. Had a gust of wind blow the truck off my jack sitting on top of a bunch of wood haha almost lost my leg. If it fell any faster Ida been screwed. And I had jack stands, just not physically holding the truck. They couldn't reach so I set them under the frame. Shoulda put them under the axle

I normally do it for any work, not sure why i deviated from my usual process.
 






what i've learned... cars are heavy.

Thanks for that important reply colintrax. Not just good advice, more like life and death. Also,
Never work under a lifted car unless it is solidly supported on stands designed for the purpose. Do not support a car on cinder blocks, hollow tiles or other props that may crumble under continuous load. Never work under a car that is supported solely by a jack.
 






Here is best I could do with my phone camera at work today.

This connection? is literally dead center in the back of the engine. Just to the right (Passenger side) is the t connection for the PCV

The hose in the picture is one of the vaccum hoses off the T connection and all of that seems to be connected appropriately?

Well, the CEL popped again yesterday. Back to the drawing board.

Lean condition procedure- P0171 System too Lean (Bank 1) P0174 System too Lean (Bank 2)
http://www.explorerforum.com/forums/showthread.php?p=2364255


Thanks for the quick links.

I have searched and read most of the P0171 and P0174 threads, and will also refere back to them. I need to go and have a rescan again because my last scan showed a P0122 code, and I want to make sure it is not repopping because of that instead of the lean code.
 






p0122 TPS code should not be related to both lean codes. Chances are you are due for new intake gaskets. GL

Well, the other day, i pulled everything off the throttle body to clean it. I am wondering if it still detects that it is not mounted securely or the wiring was damaged.


This is what I found regarding the code. Not sure it leads me to intake gaskets just yet.

Causes A code P0122 may mean that one or more of the following has happened: TPS not mounted securely TPS circuit short to ground or another wire Faulty TPS Damaged computer (PCM)

Possible Solutions Some recommended troubleshooting and repair steps are: Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary. If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics. If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.
